Abstract
Certain example embodiments of this invention relate to articles including anticondenzation coatings that are exposed to an external environment, and/or methods of making the same. In certain example embodiments, the anticondenzation coatings may be survivable in an outside environment. The coatings also may have a sufficiently low sheet resistance and hemispherical emissivity such that the glass surface is more likely to retain heat from the interior area, thereby reducing (and sometimes completely eliminating) the presence condensation thereon. The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator/freezer doors, and/or the like.
